Data Sources & Assumptions

Data

  • Sources: Migration, Weather, Remote Sensing
  • Handling different resolutions and data merge
    • all the datasets above have been collapsed at Udelaware grid 55km
    • UDelaware grid used as base: size is close to adm2-adm1 boundaries to help integrate census/admin data later
    • All rasters extracted at 55km
    • Clicim raw data aggreagted at 55km

Assumptions

  • Reducing dimensions
    • Weather: choosing months or annual values? (refer to literature)
    • months might display additional variability
    • taking annual for first cut model
    • Weather: which years to consider ?
    • Currenly taking difference from 1900 for all years overlapping with Clcim

Climate Migration: Data Notes

  • Outliers
    • Case of Tehran: 8 million emigrated in 1975
